Marine Power FAQs

Q: Can boaters use a 50Amp/30Amp adapter plug with their 50Amp Surge Guard* surge protector and hook up to a 30Amp power pedestal?
A: Yes, however, their watercraft is wired with two 50Amp/120V circuits for a total of 100Amps while the 30Amp power pedestal will only provide a total of 30Amps of power. Subsequently, only a limited number of appliances can be operated without causing circuit breakers on the power pedestal to be thrown. The Surge Guard* surge protector will provide the protection; however, the boater may experience inconvenience due to the limited power.

Q: Can I hook up a 30Amp Surge Guard* surge protector to a 240V/50Amp power pedestal using a 30Amp/50Amp adapter?
A: Yes, however, it is not recommended. The higher 50Amp input can cause the circuit breakers to be thrown.

Q: Can an watercraft owner use a ‘voltage boosting’ product in conjunction with a Surge Guard* surge protector?
A: Yes, by plugging the voltage booster into the power pedestal in front of the Surge Guard* device. The voltage booster’s primary function is to increase the voltage in low voltage situations. The Voltage Regulator is not a protective device, and the connected watercraft will not be protected from damage should an open neutral or surge develop during the course of operation. The fault indicator panel is for indication only. If the voltage booster is mounted after the Surge Guard* device, the Surge Guard* device will automatically shut off the power if it is below 102V for more than 8 seconds; subsequently not allowing the voltage booster to operate.

Q: What is the over voltage and under voltage protection?
A: When over voltage (voltage over 132V) or under voltage (voltage under 102V) conditions occur, the Surge Guard* device will shut the power off to the watercraft. This predetermined value is selected as the point beyond which electrical and electronic equipment is likely to be damaged if operated for an extended length of time. The user of any protective device is urged to be aware that protective devices are not necessarily effective for all circumstances. Bypassing for this condition can result in damage of electrical equipment on the coach.

Q: How do I know if my surge protection still works?
A: The surge protection does not usually fail unless there is a direct lightning strike. If this happens, there would likely be other obvious damage; otherwise, the surge protection should last indefinitely.

Q: What does the term "Weather Resistant" mean?
A: The term “Weather Resistant”, sometimes described as “Rainproof”, is used to describe many electrical products that are manufactured for outdoor use. Surge Guard* products described as “Weather Resistant” can be used in most outdoor environments. Please note that these products should not be submerged under water at any time.

Q: Doesn't the breaker panel in my watercraft provide electrical protection?
A: Just like in a house, the breaker panel in the watercraft is only designed to interrupt power if the amperage load exceeds the circuit rating. This does not provide any protection related to voltage changes or any sort of input wiring issues.
